It protects three-phase motors from sustained overcurrent conditions by detecting heat buildup through a bimetallic thermal sensing element. When current exceeds the set trip threshold, the relay opens the control circuit before motor windings sustain damage. Trip Class 20 means the relay is calibrated to trip within 20 seconds at six times the full-load amp setting. Licensed electricians and industrial controls technicians install this device as part of motor starter assemblies in commercial and light industrial applications.\u003c\/p\u003e\u003cp\u003eThe LR3D3561 is designed for use with LC1D80 and LC1D95 contactors, making it a direct-fit component in motor starter combinations that follow IEC design standards. It suits applications where motor loads vary or where a wide adjustment range is needed to cover multiple motor nameplate ratings within a single relay. Typical installations include HVAC fan arrays, pump panels, compressor controls, and other three-phase motor-driven equipment in commercial or industrial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThermal sensing method detects sustained overcurrent without electronic components\u003c\/li\u003e\n\u003cli\u003eWide current adjustment range of 55 to 70 amps covers multiple motor sizes\u003c\/li\u003e\n\u003cli\u003eTrip Class 20 calibration for motors with longer acceleration times\u003c\/li\u003e\n\u003cli\u003e690 VAC rating suits a broad range of IEC-standard motor control applications\u003c\/li\u003e\n\u003cli\u003eDirect-fit pairing with LC1D80 and LC1D95 contactors for combination starter builds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Schneider Electric LC1D80 and LC1D95 contactors as part of an IEC-standard motor starter assembly.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with the NEC and applicable local codes. De-energize and lock out the motor control panel before mounting or wiring the relay. Verify the current adjustment dial is set to match the motor nameplate full-load amp rating before energizing the circuit. Do not bypass or jumper the overload relay contacts during commissioning testing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensing Method\u003c\/strong\u003e: Thermal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Range\u003c\/strong\u003e: 55 to 70 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 690 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Class\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.18 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCHNEIDER ELECTRIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LR3D3561\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51540515979570,"sku":"LR3D3561","price":228.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d682fe368f3917b73160d1944c7a7db.jpg?v=1785857163","url":"https:\/\/voomisupply.com\/products\/schneider-electric-lr3d3561-thermal-iec-overload-relay","provider":"Voomi Supply","version":"1.0","type":"link"}
